Abstract
Content that is delivered nearly on-demand, in overlapping streams that start in staggered intervals on different channels, is played on-demand for the user using a storage system in conjunction with the receiver. A portion of the content corresponding to the staggering interval of the various streams is pre-cached and employed for playback when the user initiates on-demand playback. Content from the most-recently-started stream at the time of playback initiation is then buffered, and playback switches from the pre-cached content to the buffered content at a preselected alignment point.
